The series was adapted into an anime television series by A-1 Pictures during 2011 and adapted into an anime film (Ao no Exorcist Gekijouban) in December 2012. Viz Media has licensed the manga for North American production, with the first volume released in April 5, 2011. Aniplex of America also released the anime’s DVDs in English regions. A second season, titled Blue Exorcist: Kyoto Impure King Arc, is scheduled for release in January 2017.
Inspired by a Brothers Grimm fairy tale, Kato tried to work the angle of brothers fighting monsters into a story. She eventually decided on making the story about demons and exorcists, thus conceiving Blue Exorcist. Due to exorcists being the main idea of the story, the manga features a lot of Biblical references. In an interview with Anime News Network, Kato said, “I should not run away from these references if I’m working in the Exorcist genre.” An ending was planned by Kato but the exact length of the series has yet to be decided based on the manga’s popularity in Japan.
An anime adaption for the manga was announced on November 27, 2010 on Shueisha’s Jump SQ official website. The anime was produced by A-1 Pictures with Hitoshi Okamura as the producer. Originally, the series was scheduled to air on April 10, 2011 on MBS, replacing Star Driver: Kagayaki no Takuto; however, due to the March 11, 2011 Tōhoku earthquake and tsunami the series’ broadcast was delayed until April 17, 2011. The anime ended on October 2, 2011.
Four pieces of theme music are used for the episodes: two opening themes and two ending themes. The opening theme for the first 12 episodes is “Core Pride” by Japanese rock band Uverworld, while the opening theme from episode 13 onwards is “In My World” by Japanese rock band ROOKiEZ is PUNK’D. The ending theme for the first 12 episodes is “Take Off” by South Korean boy band 2PM, while the ending theme from episode 13 through episode 25 is “Wired Life” by Japanese singer Meisa Kuroki.

Aniplex of America released Blue Exorcist on DVD in four sets, starting by releasing the first DVD on October 18, 2011. An Original Animated Video has also been released in 2011, called Ao No Exorcist: Kuro no Iede. The series began broadcasting in the United States and Canada on Viz Media’s online network, Neon Alley, on October 2, 2012. The series began airing on Adult Swim’s Toonami block on February 23, 2014 and finished airing on August 10, 2014.
